The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.-

, Be it known that I,H. M. HALL, Vof Danby, in the county of Rutland,and State of Vermont, have in-` vented a new and improved Attachment forSewing- .Machines; and I do hereby declare that the following willenable those skilled in the art to make and use the same, referencebeing had to the accompanyingdrawings, forming part of thisspecification, in which- Figure l is a plan view of the attachment,.withits rods, or lingers removed.

Figure' 2 is-a longitudinal vertical section of the same, through theline :1; x of iig; 1.,

Figure 3 is a cross-section ofthe same,`tbrough the line 'y y, lig. 1.

' Figure 4 is a detail view of one of the fingers, showing the disk andhead of the same.V

The figures, from 5 to 13 inclusive, illustrate the differentcombinations of the fingers, for the different kinds of work to be done.

Similar letters of yreference indicate corresponding parts.

The object of this invention is to provide an attachment forsewing-machines, which, by the permutation of its devices, will hold, orguide the goods in any one of the severaloperations, such as'(amongothers) the operations of seaming, binding, braiding, tucking, andmarking, gathering, hemming, quilting, stitching, and others. v

The attachment consistsyin general terms, of a plate, having holders, orstandards, by means of which two or more slender rods, or lingers (someof which have peculiar devices contributing to their functions) areadjusted, and heldin the proper position for performing such functions.

The lingers are, preferably, of metal, and are about the size of largeknitting-needles, some being plain fingers, while others are providedwith accessory devices, which conduce to the peculiar office required,which, with other devices perfecting the whole, will hereinafter be morefully set forth.

In the drawings- A is the base-plate of the attachment, which is to beaixed, preferably, to the gauge-plate of the sewing-machine, or directlyto the cloth-plate of the same, in which latter case, the upturned partE serves as a gauge for the' goods to pass against, while the attachmentis on the sewing-machine.

The plate is provided with two perforated standards,A

O and l), through which the. fingers pass, the latter being arranged oneabove the other, and project over` the cloth-plate `in suitableproximity thereto.

The rear standard C is iixed, while the front standard D is movable toor from the fixed standard, in order to cause the divergence orconvergence of the fingers held in theholes of the standards, for apurpose to be shown.

'The standard D and plate A may be constructed in ,any suitable manner,to permit the said standard to4 be moved, -but I prefer, as'the simplestmode, to double over the edges ofthe plate A, as shown at B, so as to j.form grooves for the lanches a, of the two standards, vis a full, clear,and exact description thereof, which to rest in, and to serve as guidesfor the flanch of the Amovable standard, the standard (l being xcdstationary, by means of screws, or rivets passing through its rIhegeneral arrangement of the lingers will be better understood byreference to the several gures, from 5 to 13, where the particularlingers required are shown in proper combination for the work tobe done.

In order to lhold the lingers fnmlyin place, the rear standard is madehollow, and contains any elastic substance, as cork, or rubber, which,from its contractile character, clasps the fingers, and thus preventstheir accidental slipping while in use.

I prefer to use cork, as it is a material which exercises the bestfrictional eiiect on the'ngers.

There should be an additional hole in the front standard to thefinger-holes, and which is in line with the ,upper hole in the rearstandard, for a purpose to be the former is moved toward the latter, theiingers will i be converged toward each other, whereby the outer l endsof the said fingers will bear upon the goods, 'or

fabric between any set of two or more of the fingers, .and thus hold andguide the same with the properresistance outside, or beyond theline ofdraught, or cloth-feed of the sewing-machine.

I t will be observed, that either' standard may be made the movablestandard; that is to say, the standard G may be movable while thestandard D is xed, in which case the former must be made to approach thelatter, in order -to converge the lingers, the relaf tive number andarrangement of the linger-holes remaining as before.

The plate A is formed with a mortise, zZ, extending crosswise of theplate, just behind the gauge E.

rIhe mortise is for the reception of the tongue Gr, projecting from thepart H, which latter may consist of a slotted plate, or of a wire bentdouble, to obtain a longitudinal opening analogous to and serving as aslot for the clamp-screw, or screws, which tix it to the cloth-plate,o1' the usual gauge ofthe sewing-machine, if desired.

It will be observed, that the plate A may be adjusted laterally on the'tongue G, in order to bring the fingers at the proper distance from theneedle, which is represented by the red dot b in fig. l, showing. thegeneral relative position of the lingers and gauge E,

with reference to the needle of' the sewing-machine,

when the attachment is in use.

This mortise d may be formed in any suitable man? ner, or may consist oftwo or more wire loops, bent,

-plate; but all of these different modifications would be. simplymechanical equivalents of' the device which I prefer to use for thispurpose, as being, perhaps, the simplest and easiest made, and which is,to cut away the upturned edges B, just in rear of the gauge E, to

` the required distance, and afiixing at this part a plate,

e, bent as shown, and afixed, either by rivets or solder, to the gaugeE, and to the base-plate, as shown.

The object of this device is to enable the'base-plate to be held in theproper position above the cloth-plate, without being 'attached thereto,when certain operations," or the construction of certain machinesrequire it, in `which case the part H will be clamped to some fixed partof the machine, which lies above its clothpiate.

The fingers are plain, slender, cylindrical ro'dspref erably of steel. Y

Onev end ofthe fingers is provided with devices conducing to certainspecific functions.

These. devices consist, in general terms, of heads, disks, apencl-holder,a cross-bar, or stop-bar, and a quilting-point.

For convenience, and to reduce the number of sepaf rate parts, thesedevices are applied on, Vor near one en d of the fingers,- while theother ends are available as: plain fingers, when such are required.

This combination reduces the number of separate fingers to only five,with which they are made to assist the sewing-machine in twelve orthirteen dierent operations.

Two of' the fingers bear, each at one end, a cylindrical cap, e, asshown.

To each of these caps is aixed, by solder or otherwise, a disk, orbutton, f, which is placed back from the rounded end of the cap.

One of such fingers is shown in the detail view of' fig; 4, and thesefingers will be called, in succeeding description, the head-fingers, ordisk-fingers, according as either device is employed to perform itsparticular function, in coinbination with other fingers, or togethersimply. l

When the plain ends of any of the fingers arev employed in suchcombinations, they will be denominated simply as plain fingers, as thedevices which they bear -at their other ends will not then be in use.

The cross-bar fingerg is provided with a short wire cross-bar, h, atxedto it at a short distance from one end,.as shown in the several figures,5, 6, 8, 9, 12, in a portionof which figures the cross-bar is, however,not in use, its finger g merely serving as a plain linger.

The marking-finger i isprovided with a pencilholder, j, which is aplate, afhxed to one end, and provided with a screw, t, to protrude thepencil-point, located in the same hole, as shown in dotted outline.

The upperpart of the plate j is formed with a recess, for inserting theend of one of the plai-n fingers, in order. to steady the said plate andits contained pencil, and the additional hole in the front standard, asbefore mentioned, is torcceive this finger.

The remaining finger, l, has a bent varm, m, to serve as a guiding-pointin quilting, which-willbe more fully described hereinafter.'

The several combinations of lthese dierent fingers;

which are employed for certain operations, will now be speciallydescribed by reference to the several iigures, from 5 to 13 inclusive.

Fig. 5.--T0 sew several pieces in one seam.

In this combination plain fingers only are used,'one more linger beingtaken than there arel pieces of cloth to be run together.

The cloth is inserted between the fingers, as shown by the red lines,with the edges to the gaugefface, which can be set out any distancerequired for width of seam.

When this is done, the machine is started, and the cloth will run alikeon. the edge, if the work is not permitted rto drag, which should bekept loose in front ofthe gauge.

lt' light work is being done, it will run by itself much better thanwhen assisted by the operator.

Should any of the pieces be inclined to double at the edge, withdraw thelinger just above it.

Set the gauge for width of seam, and have the needle catch b 'oth piecesof' cloth.

kRemove the work. when sewed, and fell it down by hand, or with thefeller, or hemmer, on the foot of the machine.

Place the goods between the plain fingers kand th`e staying, in thespace between the shoulder of the cap, or head, and the gauge E.' v

This space can be made any reasonable width, by pushing out the fingers.l

Insert the goods, as shown bythered lines, and converge the lingers, bymoving the standard D, as before described.

One plain finger, the barred finger g h, and headed finger e, arrangedas.v shown, with the bar h turned downward, and about one-half thevwidth of the braid distant from the gauge..

lThe head e is placed from the gauge the widthof the braid. A

The goods are inserted below the barred linger, with the edge againstthe bar h.

After being sewed, the braid may be turned by hand, or between any twoofthe fingers.

Plain nger below, barred finger next above, and

tween it and the head e.

The cloth is placed between the-plain nger andthe barred finger.

The bar le is set outfrom the gauge E the distance to which the braid isto be put on from the edge of the cloth which runs against the gauge.

The bar la, is set from thehead the width of the braid.

Should it be required to put on braid over two inches from theedge, theplate A will have to be held from above, so that the work lcan go underto any desired distance, instead of being between the plain iinger andthe barred fin ger.

The work can then be gauged by inserting the ny Fig. id mdmg.

The two disk-fingers f f, with the disks, turned face to face, anddistant from the gauge half the width of the braid. l

The cloth is placed between the heads e.

The lower finger should be placed in the first holes, and the upper onein the third holes.

The gauge should' be arranged to extend along the side of thepresser-foot, as far as the needle, or the binding will'slip out beforeit gets te the needle.

The binding shouldbe caught in the work just as it.

is to be done, and to slip between the heads, taking care to have theedges of the braid in the space between the disks.

Either lip of the binding can be made the longest, by placing one headnearer the gauge than the other.

The pencil-plate is set as far out from the gauge as the width of thetuck. v

The gauge E is to be set the width ofthe tuck from the needle, and.alongside of it, to prevent variation after leaving the ingers Quilting.

Hang the plate from above, and run lthe work under, using the arm m, ofthe finger l in, as a guid; to follow the previous seam. l

It will be observed, that in each of the above combinations, the fingersmust be converged, so as to pinch the goods held between them.
